    Expanding gas streams

    Sascha Albrecht

      I have an expanding gas stream in my fluid simulation.

      The gas in the expansion is always very hot (1000 K or more) but the boundary condition is air at 392K.

      It doesn't matter whether I'm using an pressure at the inlet or a mass flow.

      Especially at pressures below atmospheric pressure that seems to be a problem.

      Is there a good strategy to get the temperature right?

       

      Thank you
